The former Strictly Come Dancing star turned to the host and laughed before turning away to face the board in embarrassment.

The rude innuendo is just one of the cast’s many outbursts over the years, according to the host.

Rachel previously admitted the Countdown cast are sometimes forced to re-do takes due to their saucy antics.

She previously told Express.co.uk: “Sometimes we have to re-do things.

“At the same time rude words coming out, I’ve got the gallery upstairs, who are the filthiest people that you’ll meet, trying to make me laugh or if you’re trying to keep a straight face, there’s 10 people in your ear wetting themselves. Then it can be a bit harder.”

The blonde beauty also addressed the moments she had been left red-faced thanks to a rude word being spotted amongst the bundle of consonants and vowels.
